If a potato is placed on a pure paper plate which is white and unprinted and put in a microwave oven, the potato heats up but the paper plate does not. This is because:

(a)

Potato is mainly made up of starch whereas paper is mainly made up of cellulose

(b)

Potato transmits microwaves whereas paper reflects microwaves

(c)

Potato contains water whereas paper does not contain water

(d)

Potato is a fresh organic material whereas paper is a dead organic material.

Answer:

(c)

CA

Explanation

The reason why the potato heats up but the paper plate does not is due to the difference in their material properties. Potatoes contain a significant amount of water, which allows them to absorb the microwaves and convert them into heat. The microwave radiation causes the water molecules in the potato to vibrate and generate heat, which cooks the potato.
